多个 support-v4 jar 导致问题

Question

我已经从 Eclipse 中导出了一个项目 - 但现在我无法将支持库添加到我的项目 compile 'com.android.support:support-v4:21.0.0' 因为在这个项目中使用的库有自己的同一个库的副本（但他们有它在一个libs 文件夹中的 jar 文件）。现在，当我添加 compile 'com.android.support:support-v4:21.0.0' 时，我遇到了这个问题：

Error:Execution failed for task ':Athan:packageAllDebugClassesForMultiDex'.
> java.util.zip.ZipException: duplicate entry: android/support/annotation/IntDef.class

有人可以帮我解决这个问题吗？

这是我的应用 build.gradle

apply plugin: 'android'


dependencies {


    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':google-play-services_lib')
    compile project(':library_viewpager')
    compile project(':sliding_library')
    compile project(':android-support-v7-appcompat')
    compile 'com.android.support:multidex:1.0.0'
    compile 'com.android.support:support-v4:21.0.0'
}

android {
    compileSdkVersion 21
    buildToolsVersion "22.0.1"

    dexOptions {
        preDexLibraries = false
    }

    defaultConfig {
        multiDexEnabled true
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')

        // Move the build types to build-types/<type>
        // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
        // This moves them out of them default location under src/<type>/... which would
        // conflict with src/ being used by the main source set.
        // Adding new build types or product flavors should be accompanied
        // by a similar customization.
        debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

仅在库项目中添加支持 jar。无需在主项目中添加它，并记住所有支持库应该是相同的版本
